I'm trying to identify a book from my childhood that I vaguely remember.  I remember that it involved racing ships against each other around various planets, where they would land on planets and refuel/repair.

Funny thing is, I can't remember if it was actually good or not; I kind of want to read it again, but I am wondering if it is like the Dark Crystal movie, and better left in my memory (re-watching that years later was a mistake...I remember it being such a good, exciting movie.  Oops).
